Unidata McIDAS-X Users,

A jumbo addendum to Unidata McIDAS, Version 7.804, is now available
for download.

The 7.804 addendum contains all Unidata modifications and additions to
Unidata McIDAS 7.80 since its initial release in August in addition to
all SSEC 7.8 addenda.

Highlights of the changes 7.804 include:

o sites can now use the GNU Fortran compiler, g77, in combination with
  the GNU C compiler, gcc, to build McIDAS-X and McIDAS-XCD.  Builds
  using the gcc/g77 combination have been extensively tested on
  Sun Solaris platforms (SPARC and x86).  Other Unidata-supported
  platforms have been tested for McIDAS-X, but not for McIDAS-XCD.

  NOTE: Sites that have vendor-supplied compilers available are advised
  to continue using those compilers.  Performance tests conducted in
  the past by SSEC indicated that code compiled with gcc may not perform
  as well as code compiled using vendor compilers.

o a number of new map outline files have been included.  These provide
  support for US highways and interstates; US state roads; US railines;
  US canals; US and world rivers; major world lakes; much higher
  resolution US counties; and global tectonic plate boundaries.

o new, higher resolution versions of the US State, County, and Zone

o 37 new grayscale and color image enhancements.  These were created from
  definitions available on the CSU/CIRA site:


o augmented functionality in the MCGUI interface which includes new
  ADDE server sites for MCGUI-supported datasets; access to the new
  image enhancements; saving and restoring frame contents in McIDAS
  PIX format; and an interface to the AREA file dump routine, AXFORM.
o numerous bugfixes and program enhancements for -X and -XCD functions

More detailed information on the modifications made in 7.804 and
instructions for its installation can be found in the Unidata McIDAS-X
Addenda pages:
